I suffered 2.5 years with stricture/ fistula problems. My NY surgeon dilated the stricture & put seton in for Perianal stricture. It was so uncomfortable had it removed. After a few weeks still had stricture & fistula problems went to a different NY surgeon 1 yr later. He dilated & cleaned the area out said not to do anything with the fistula. Put me on 2 antibiotics. Heavy doses of flagyl/ Cipro and the fistula cleared up on its own- in a few weeks. I really was amazed. I'm still having stricture problems. My insurance changed and waiting to go back and get stricture done again.
